STD 5 : Series and Parallel Circuits

The picture shows an electrical circuit. This circuit is a series circuit because:

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

A series circuit has ____ path(s) that the electric current can take.

• One

• Two

• Three

• Four

This is an example of a _______ circuit

• open

• series

• parallel

• switch

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.

• The other bulbs will stay on

• The other bulbs will get dimmer.

• The battery will become stronger.

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.

• parallel

• series

• open

• closed

This is an example of a _______ circuit

• open
• series
• parallel
• square

This is an example of a ______ circuit

• Series
• Parallel
• Open
• Dihexihedral

What is the definition of electrical current?

• The opposition to the flow of electrons

• The rate of flow of charge

• The work done on each coulomb of charge

• Electrons moving around

• Series circuit - Bulbs are lit
• Series circuit - Bulbs are off
• Parallel circuit - Bulbs are lit
• Parallel circuit - Bulbs are off
